WALL GONSTRUGTION Application filed October 20, 1928. Serial No. 313,801.

This invention relates to wall constructions for bulldmgs of various kinds and classes, and particularly to concretewalls;

.10 structure and furtherto insulate the wall from both heat and cold; a further object being to provide arwall structure of the class described, one wall of the chambers or compartments therein being lined with a body of fireproof material such for example as asbestos; a further object being to provide core members of inexpensive material with means for positioning or alini'ngsaid core menibers to provide continuous passages vertically through the wall structure in continuous or irregular fashion, the core members arranged in one plane of the wall structure being in staggered relation with reference to those arranged in another plane, thus completely shielding the entire wall structure and yet providing a binding of the concrete body constituting the inner and outer faces of the wall structure; and with these and other objects inview, the invention consists in a wall structure of the class and for the purpose specified which is simple in construction, efficient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specificationof which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable referencechairacters in each of the views, and in which Fig. 1 is a plan and sectional view of a part of a wall made according to my invention.

V Fig. 2 is a partial section on the line -2-2 of Fig. 1.

Fig. 3 is a perspective view of a modified arrangement of core members which I employ.

e0- Fig. 4 is a perspective view ofone-of a number of core members employed with part of the construction broken away; and

Fig. 5 is an enlarged sectional detail view showing adjacent ends of two cores.

My invention relates tothe formation of continuous or communicating chambers extending vertically through the wall structure and spaced longitudinallyas well as transversely thereof and particularly to the manner of forming such chambers in the wall to facilitate the molding of the concrete or reinforced concrete wall structure and to accomplish this result in the simplest and most economical manner.

To this end, I employ a plurality'of core members one of which is shown in detail in Fig. 4 of the drawing and is designated by the reference numeral 5/ At this time, it will be understood that the members 5. may be of any desired dimensions both as to height, Width and thickness, the same being made .to suit the particular type of wall structure to be formed. and while these members are preferably rectangular in form, they may be made of other contour. In practice, these members are made up of an inner substantially rigid plate 6, preferably of heatresisting material, such for example as sheet asbestos or an asbestos compound.

Arranged outwardly of this sheet are a plurality of corrugated sheets all designated at 7 three of which are shown in F ig. 4 of the drawings.

These sheets are subdivided by vtwo flat sheets 8 arranged between the central and inner and outer corrugated sheets 7 The sheets 7 and 8 may be composed of any suitable material but are preferably composed of inexpensive paper or cardboard such as com- .monly employed in the construction of corrugated boxes, wrapping paper and the like.

On the outer face of the outer corrugated sheet 7 is arranged a facing sheet 9 of paper, cardboard or the like preferably treated with a wax, paraffin or similar substance to render the same moisture proof. This sheet may constitute a sheet of tar paper or a paper treated with a pitch or other base. The sheet 9 is preferably wrapped over the'opposite sides of the memberb. as seen at'10 and over the top edge thereof as seen atv 11 so as to prevent the concrete from passing into the chambers 12 formed between the corrugated sheet 7 and the sheets 8, 6 and 9, especially at the top of the member 5 in the operation of pouring concrete downwardly around the walls of a number of said members in the operation of forming the wall structure. However, when one cast or mold has been made to a height equal to the height of the members 5, it is preferred that the top sheet 11 be torn off prior to placing the next member 5 thereon in building up the wall structure. The adjacent ends of two'cores with the top sheet 11 removed as shown in detail in Fig. 5 f the drawing. IVith this fact in mind, it is preferred that the height ofthe members be equal to the height of a molding operation to be performed in the wall structure. However, this is not absolutely essential as a number of these core members 5 may be placed one upon the other in performlng such an operation.

It is also to be noted at this time that in arranging the members 5 in the manner seen in Fig. 3 of the drawing in the formation of a wall, that part of the upper edge of each member which is not covered by the other members 5 placed thereon is left'protect'ed or covered by the top sheet 11. i

In molding the concrete wall structure 13 shown in Figs. 1 and 2 of the drawings, the core members 5 arranged in the respective inner and outer planesdesignated by the reference characters 00 and 002 are placed directly one upon the other to form continuous vertical chambers in the wall structure. Between these chambers, the spacing of the members 5 form vertical columns 14 in the concrete wall structure adjacent the inner face of the wall and in alinement with the plane a: and similar columns 15 outwardly of the columns 14 in the plane 502 the latter being arranged intermediate the columns 14 i by virtue of the arrangement of the core the inner and outer surfaces of the concrete wall structure also provides a completely shielded wall structure to check and retard any seepage or penetration of moisture through the wall structure from the outer surface thereof to the inner surface, thus maintaining the inner surface in a dry state at all times, it being understood that any transmission of moisture through the wall from the outer surface thereof will follow the course of least resistance and will thus be picked up by the chambers in the outer plane :02 or the chambers in the inner plane as formed by the core members5. I

At this time, it will be understood that the outer facings 9-which are treate'd to render the same moisture proof will be of such texture as to perform this function primarily in the setting of the concrete, but not sufiicient to withstand moisture for an indefinite period of time, thus breaking up and deteriorating, leaving nothing but the chambers in the wall structure. On the other hand, the moisture reaching the facings 9 will pass downwardly along said facings and be discharged at the base of the wall structure. In the same manner, excessive hot or cold temperatures existing externally of the building wall, subject to transmission through the wall, will bechecked by the asbestos sheets arranged on the inner faces of the core members or on the inner faces of the chambers formed-b said core members. r I

In. constructing the members 5, the number of corrugated sheets? and the texture of .saidsheetswill govern the pressure resisted moisture resisting and temperature resisting properties of the wall structure.

7 In Fig. 3 of the drawings, I have shown a modified arrangement of the members 5 which instead of being placed one directly upon the other in the separate planes -002 as in the construction shown in Figsal to 3 inclusive, said membersare arranged in the alternate rows or lays in spaced relation. For example, the. members 5 in the bottom row designated at y andthe third row designated at g 2 are in common vertical alinement but in spaced relation to the members 5 arranged in the intermediate row 3. However, the side 'portio-nsof the members 5 in the row y?) overlap and are in alinement with the side edges of twoadjacent members 5 in each row g y2 thus forming a continuous communication between the chambers formed by the members 5 in each plane 0a m2 verti- ,cca'lly through the wall structure. preferred thatthe members5 in the plane 002 bearranged in staggered relationto the :members 5. in the plane 00 in the respective rows so that the members 5 of the outer plane 502 are arranged inalinement with the body of concrete positioned at 16 between the spaced members 5 in each row 3 ,g 2 and 3 3. In like manner, the members 5 arranged in the plane w are in alinement with the bodies ofconcrete arrangedbetween the members 5 in the plane w2as designated at 17. H

In both forms of construction, the wall structure is composed of reinforced concrete and any suitablemeans may be employed for maintaining the core members 5 in proper It is also position in the operation of pouring the concrete, for example, the reinforcing rods 18, 19 and 20 may all have spacing members designated at 21 for properly positioning the core members 5 and in addition, the core members may be maintained in vertical alinement by U-shaped keepers 22 having upwardly and downwardly directed channels receiving adjacent ends of said members.

From the foregoing, it will be apparent that hollow concrete wall structures may be formed in a very simple economical manner, and while I have shown and described one specific form of core member, it will be understood that my invention is not limited to the specific structure herein disclosed nor am I limited to any particular arrangement of the core members in the wall to be formed, and various other changes in and modifications of the construction herein shown and described may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
